Settings | Details |
Name | The widget name is the parameter name, and it is set as English by default. The name needs modifying according to the actual parameter. |
Font Size | The font size of the content in the widget defaults to 12 px. |
Data Dictionary | It is used to add options of the widget. You must set it, otherwise the widget will not display options. For how to set it, see Data Dictionary. |
If you tick Remove Duplicates, it will merge the same items in the drop-down options. Otherwise, it will not merge them and will keep the duplicate options. It will be ticked by default. | |
Default Value | You can set the displayed default value of Check Box Group Widget, which supports the following three types. 1. Custom String: You can input text directly, and when you enter multiple values, multiple options can be ticked. When you enter multiple values, the format needs to be consistent with the widget's Return type. When the return value is not modified, it is separated by a comma in English by default, such as: East China,North China.
2. Field: You can select field in the dataset. If a field has multiple values, multiple selections will be made.
3. Formula: Click fx on the right side to enter the formula. If the formula corresponds to multiple values, multiple selections will be made.

Return | Array: The return type is an array, for example: if three values are ticked, the return value will be:value1,value2,value3. |
String: The return value type is a string, and it needs to define the Separator, Starting Symbol, and Terminator. That is, multiple values that are ticked will be concatenated into a string according to the separator. Example: If the separator is defined as a comma, the starting symbol and terminator are both defined as single quotes, the return value will be value1,value2,value3.

Layout | There are following three types you can choose. 1. Auto Fill: It can automatically adjust the number of rows and columns based on the option content. 2. Fixed Columns: It can be set to display as n columns. The default is one. 3. Fixed Rows: It can be set to display as n rows. The default is one. |
Permission | It is used to decide whether the widget is editable when previewing. The default option is editable. |
